Fully Installed Explosion-Proof Standard Safety Is Extremely Strong Explosion-Proof Type Pressure Transmitter
An explosion-proof pressure transmitter refers to an instrument whose electrical components (such as circuits, wiring terminals, and housing) have been specially designed, manufactured, and certified to operate safely in explosive gas, vapor, or dust environments without becoming an ignition source.
Main explosion-proof types (protection types)
For pressure transmitters, the most common combinations are: Flameproof type (Ex d) or Intrinsically safe type (Ex ia/ib).
Example of explosion-proof marking interpretation: A complete explosion-proof marking contains all safety information. For instance: Ex d IIC T6 Gb
The core differences between explosion-proof and non-explosion-proof transmitters
| Characteristics | Explosion-proof pressure transmitter | Ordinary (non-explosion-proof) pressure transmitter |
|---|---|---|
| Design standards | Follow strict explosion-proof standards (such as IEC 60079) | Follow general electrical safety standards |
| Shell structure | Extraordinarily robust, with precise mating surfaces and pressure relief/explosion-proof design | Ordinary protective shell (such as IP67) |
| Internal circuit | May have intrinsically safe design (intrinsic safety type) | No special energy limitation |
| Certification | Must obtain explosion-proof qualification certificate | No explosion-proof certification required |
| Cost | Significantly higher (design, material, certification costs) | Low |
| Application sites | Explosive hazardous environments | Safe areas or non-hazardous environments |
| Installation and maintenance | Have special regulations (such as tightening torque, grounding) | General electrical regulations |
Explosion-proof pressure transmitters are the "guardian angels" and "legal red lines" for safe production. The selection and application of them are not issues of optimizing technical performance, but rather mandatory safety guarantees under the law.
